Condensation particle counter for number concentration up to 7 • 104 particlescm3 (single count mode) and 107 particlescm3 (photometric mode)
The UF-CPC 100 measures the total particle concentration of ultrafine particles and nanoparticles suspended in air or other carrier gases. These particles are enlarged by a condensation process in order to enable the precise determination of their number with an optical light scattering detector. The working fluid, e.g. butanol or water, is vaporized as a condensation agent. The nanoparticles to be measured are directed through the vapor atmosphere, during which the vapor condenses on the nanoparticles in a cooling zone. The condensation process is influenced by the nanoparticles themselves, as well as the working fluid, the operating temperatures, and the volume flow.
In addition to their number, the UF-CPC 100 also measures the size of the droplets and provides the user with additional information concerning the condensation process. This novel and patented (German patent no.: DE 10 2005 001 992 A1) working fluid delivery system provides greater flexibility. The user is no longer limited to butanol or water, but may also opt for more environmentally friendly or better suited working liquids for special applications.
